    P2O5.BaO.Na2O.K2O glasses doped with various content of Eu2O3 were prepared using high temperaturemelting method, and the Eu 2+ ions in the phosphate glasses were obtained with the aid of the reductiveaction of silicon powder. The fabricating conditions, fluorescence, excitation spectra of the glasses werethen studied. The glasses containing europium show a broad emission band at 450 nm and sharp bandsfrom 580 to 650 nm, and the co-existence of Eu2+ and Eu3+ is identified. Also, a good glass with adominant proportion and large quantity of Eu2+ ions can be obtained by the reductive action of siliconpowder and proper processing.
